Background
Hydrogen fluoride is a colorless gas; at 80 ℃ or lower, an association (HF) n is formed due to hydrogen bonds between molecules; anhydrous hydrogen fluoride is extremely corrosive; when a small amount of water vapor exists, the high chemical activity is displayed; liquid hydrogen fluoride has a very high dielectric constant, is an excellent solvent, and can dissolve many inorganic and organic compounds; is an important industrial chemical product! The physicochemical property of the industrial hydrofluoric acid determines that the aqueous solution of the hydrogen fluoride is colorless and easy to flow liquid, fuming in the air, having strong corrosivity and toxicity, and being capable of eroding glass and carbon steel equipment, so that a large amount of carbon steel equipment is corroded and damaged by the carbon steel equipment in the hydrogen fluoride production process, the mixture of the fluorite powder and the concentrated sulfuric acid is basically converted into a byproduct tailings of the reaction of the fluorite powder and the concentrated sulfuric acid when reaching the other end of the hydrogen fluoride reaction furnace, and the tailings are spirally discharged through slag discharge. The generated by-products contain a large amount of hydrogen fluoride gas and volatile gas of sulfuric acid, which greatly affects the surrounding environment and brings huge economic loss to enterprise production. Traditional investigation system is generally all at pipeline below opening, and the tailings is discharged from the pipeline opening part through the spiral of slagging tap, and in this kind of mode of slagging tap easily made the moisture in the air get into the pipeline, in moisture and the pipeline hydrogen fluoride and the sulphuric acid reaction, very easily corroded equipment, not only incremental cost, influence production moreover.
